Parametric Study of Factors Affecting Design and Thermodynamic Characteristics of Induced Draft Cooling Towers

Rupsha Bhattacharyya

Abstract


Induced draft cooling towers are an important direct contact heat transfer utility system at every process and power plant and they represent an important capital investment for any facility. Therefore, their design has to be done carefully using accurate design data. This work studies the effect of the most important design parameters on the final design and thermodynamic performance of the cooling tower (i.e. the air flow rate required, the tower diameter and the packed height) for meeting an assumed constant heat load throughout the year. Use of actual meteorological data for a specific location and vendor design data reported in open literature is made for these calculations. The code developed here can be used for optimization of cooling tower design and can be extended to design of cooling water networks as well.
